25 Easy Vegetarian Recipes Handy for Houseguests Who Turn Up Unannounced This Season

An unexpected guest can leave dinner plans uncertain, especially when you need more than a snack. From salads and dips to filling pasta, potato sides, and simple sweets, the options span a range of occasions and prep times. A quick bite can cover a short visit, while a casserole, soup, or baked dish can anchor a longer meal. Familiar ingredients make it easier to choose something that suits the time you have.
